This mountain map has been produced in collaboration with the association Laponiatjuottjudus, which manages the Laponia world heritage, which includes the Muttos National Park. The scale of the national park is 1:50,000, while the reverse, which shows large parts of the Sjavnja nature reserve, is at a scale of 1:100,000. We have come to the conclusion that the best material for a map is Tyvek®. It is made of a synthetic fiber that makes the map completely insensitive to water and very tear-resistant. A Tyvek map will not tear in the folds or lose color when you use it.
